Class

||||||
|
Foam::fv::tabulatedNTUHeatTransfer
|
||||||
|
|
||||||
|
Description
|
||||||
|
Tabulated heat transfer model.
|
||||||
|
|
||||||
|
The heat flux is calculated based on the Number of Thermal Units (NTU).
|
||||||
|
A 2-D table of NTU as functions of the primary and secondary mass flow
|
||||||
|
rates is required.
|
||||||
|
|
||||||
|
The exchanger geometry can be specified using either:
|
||||||
|
- \c calculated:
|
||||||
|
- inlet area of each region and core volume determined by interrogating
|
||||||
|
mesh patches, and mesh-to-mesh interpolation volume
|
||||||
|
- calculated core volume canbe partially blocked by specifying a
|
||||||
|
\c coreBlockageRatio [0-1] entry
|
||||||
|
- \c user:
|
||||||
|
- inlet area of each region privided by the user
|
||||||
|
- core volume automatically calculated by the mesh-to-mesh
|
||||||
|
interpolation volume if not provided by user
|
||||||
|
|
||||||
|
Heat transfer coefficient calculated by:
|
||||||
|
|
||||||
|
\f[
|
||||||
|
htc = C_{min} \frac{NTU}{V_{core}}
|
||||||
|
\f]
|
||||||
|
|
||||||
|
Where \f$ C_{min} \f$ is given by:
|
||||||
|
|
||||||
|
\f[
|
||||||
|
C_{min} = min \left(Cp_1 \dot{m}_1, Cp_2 \dot{m}_2 \right)
|
||||||
|
\f]
